Question

编写函数，删除字符串中间的星号（*）。函数声明为： void delete(char *s);

Answer 1

// 假定参数s指向以0结尾的C语言字符串
void delete(char* s)
{
if(s!=NULL)
{
char* p = s;
char* q = s;
while ((*q)!=0)
{
if((*q)!='*')
{
if(p!=q)
{
(*p)=(*q);
}
p++;
}
q++;
}
(*p)=0;
}
}

Answer 2

//delete 命名有问题，我改成deletes(char *s);了

#include <stdio.h>

void deletes(char *s)
{
int i=0;
char *string;

string = s;
while(*s){
if(*s != '*')
string[i++] = *s;
s++;
}
string[i] = '\0';
}

int main()
{
char s[]="fusfs*** fskdfjskd***fsdfsdsdfsd*****fsdf sdf****";
deletes(s);
printf("%s",s);
return 0;
}

Answer 3

void delete(char *s)
{
int i,j;
for(i=0;s[i]!='\0';i++)
{
while(s[i]=='*')
{
for(j=i;s[j]!='\0';j++)
s[j]=s[j+1];
}
}
}

void delete(char s[],char c)//c为要删除的字符
{
int i,j;
for(i=0;s[i]!='\0';i++)
{
while(s[i]==c)
{
for(j=i;s[j]!='\0';j++)
s[j]=s[j+1];
}
}
}
